Lewis N. Clark 20-Pack Laundry Soap Kit

The great thing about this travel detergent is that it allows you to pack less clothes for a trip. Also, your luggage gets lighter over time, since each day when you wash your clothes, you discard one packet of detergent. It's also very cheap at about 50 cent per pack.For a trip, I'd also bring along some nylon rope to hang your clothes. No need to buy those expensive travel clothesline. Buy some plain nylon rope (non-colored) since the coloring from the rope can transfer onto your clothes when wet.Btw, while on vacation, I recently tried to wash my clothes with just regular liquid body soap. Surprisingly it works pretty well. I might skip taking along the detergent packs next time and just use regular soap. This will save even more weight.

I tried to find these locally but couldn't, so I ordered them online from Amazon. These are great for travel; the thick pouches mean that they won't leak or accidentally puncture, and they are great for hand washing in the sink if you dilute the soap and only use a small amount. Since this comes with 20, I know they'll last a few years.
